Given numbers are 781,860,782,478

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 781,860,782,478 is 62765955340.

Find LCM of 781,860,782,478 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 781 x 430 x 391 x 239 = 62765955340

Therefore, the lowest common multiple of 781,860,782,478 is 62765955340.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

781 x 860 x 782 x 478 = 251063821360

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

781 : 1, 11, 71, 781

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

782 : 1, 2, 17, 23, 34, 46, 391, 782

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,860,782,478, is 1.

Now, the common factors can be found like this.

781:11x 71

860:2x 2x 5x 43

782:2x 17x 23

478:2x 239

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 251063821360/(1x4)

LCM = 251063821360/4

LCM = 62765955340

Thus, we can understand that the LCM of 781,860,782,478 is 62765955340.
